SEED-PLANTING MACHINE.

SPECIFICATION forming part of Letters Patent No. 290,389, dated December18, 1883,

Application filed August 16, 1883. (No model.) I

To all whom it may concern.-

Be it known that I, JONATHAN W. BRIG- HAM, a citizen of the UnitedStates, residing in the city of Rockford, in the county of Winnebago andState of Illinois, have invented' new and useful Improvements inSeed-Planting Machines, of which the following is aspecification.

This invention relates to that' portion of a seed-planting machineemployed in the distribution of the seed, and of that class designed todeposit a grain at atime ina furrow prepared to receive it, or todeposit a grain at a time in a receptacle from which to be deposited infurrows in hills at proper intervals in proper quantities.

The object of this invention is to produce at a small cost asingle-grain dropping-machine of a reliable construction and capable ofuse in perhaps all machines designed for depositing at proper intervalsa single seed in drills, or a given quantity at proper intervals inhills, in line, or in check-rows. To this end I have designed, arranged,and constructed the seed- 2 5 distributing machines represented in theaccompanying drawings, in which- Figure 1 is a plan view with lid orcover of seed-box removed. Fig. 2 is an elevation with one side ofseedbox removed. Fig. 3 is a 0 transverse central section on dotted line00 on Fig. 2. Fig. 4 is an isometrical representation of the slottedtransverse vertical divisionwall in the seed-distributing compartment ofthe seed-box. Fig. 5 is a lengthwise vertical 3 5 section on dotted lineg on Fig. 1. Fig. 6 is an isometrical representation of the fixed diskwith its actuating-cams; and Fig. 7 is an isometrical representation ofone of the pivoted seed-pickers. v

In the figures, A represents the sides; B, the ends; 0, a lengthwisedivision-wall; D, the

bottom; E, an inclined inner bottom, and F a slotted transverse verticaldivision wall. These several parts are suitably joined, pro- 5 ducing aseed-box having a seed-receptacle, H, with inclined bottom E. A chamber,I, from which the seed is distributed, and which chamber is connectedwith the seed-receptacle H by means of an opening, K, (represented indotted lines in Fig. 2,) cut in the lengthwise vertical division-wall O,and an outlet-chamber, L, connected with the distributing-chamber I bymeans of the slot N, formed in the transverse wall F. Thisoutlet-chamber is provided with an outlet-opening, P, out through thebottom E to permit the seed to drop from the chamber, all of which aresubstantially the same as the seed-boxes shown and described in PatentNo. 208,885, dated October 15, 1878, issued to myself, Jonathan W.Brigham, and Theodore M. Flenniken, for improvement in corn-planters.

At R is represented a seed distributing wheel of disk form producedinparts, in which arepresents a disk recessed on one side, pro. ducing aperipheral rim, b, and its center is provided with an axial hub, c,centrally bored to receive an axial shaft. This disk is also provided atproper intervalswith studs d rising from its recessed face. I11 thisdisk-formed 7o distributing-wheel, 6 represents a disk fitted toreceivethe hub c of the disk at and enter snugly within the peripheralrim b thereof and rest on the studs d, to which it is fixed by means ofsuitable screws, producing a wheel of disk form having an internalchamber, h, between the two disks. The peripheral rim b of thisseed-distributing wheel is provided at proper intervals with openings tcut through the rim, having end walls of curved 'form produced from thecenters 70 within the rim, and these openings communicate with theinternal chamber of the wheel, and the portions of the rim between theopenings cut therein are beveled on each side, as represented at l. Therecessed disk a of the seed-distributing wheel is provided withsegmental slot-openings on having their curved side walls produced fromthe centers is. The seed-distributing wheel is provided at properintervals with a seed-pick- 9o ing device of the form represented in thedrawings, consisting of a segment-arm, n, and aradialarm, it, having athickness slightly less than the depth of the internal chamber of theseed-distributing wheel. The end of the ra- 5 dial arm a is pivotedwithin the chamber of the wheel on the center k, near its peripheralrim, in which position the outer portion of the segment arms n enter theopenings 1' in the rim of the wheel in a free manner to I00 permit of afree oscillatory movement therein. The extreme outer end of thesegment-arm at a is enlarged in thickness, and is provided at n with abeak, which overlaps the peripheral rim of the wheel, and its inner facein the angle formed with the segment arm is concave to receive the seedbetween the inner face of the beak and the outer or peripheral face ofthe wheel. This seedpieker, at the IO junction of the segment and radialarm in the inner angle formed thereby, is provided with a stud-arm, 0,projecting at a right angle with the side face of the arms and in suchposition that when the picker isin place. the stud-arm 0 will extendthrough the segment-slot openings m in the disk.

At T is represented a disk-cam, provided with a central hub, 12, boredto receive a shaft to revolve therein. This disk is provided with acontrolling guide-rim, p, projecting from its face side concentric tothe axis of the disk, and in position thereon to receive the projectingstud-arms 0 of the pickers to limit their outward movement.

At p is represented an irregular cam-rim projecting from the face of thedisk eccentric to its axis, and in position on the disk to receive thestud-arms 0 of the pickers in the rotations of the wheel to project thepickers to discharge the seed.

At 8 is represented a curved lever, having a free pivotal connection ats with the disk at its upper side in such a manner as to permit of alimited movement about its pivotal support, and in such position on thedisk that its inner curved surface will engage the studarms 0 of thepickers when in their rotations they leave the concentric guide-rimp,and operate by the action of gravity to press inward on the stud-armsand hold the pickers inward to grip and hold the seed. This disk-camwith its cam and guides is fixed in position in the seed-distributingchamber of the seed-box to the vertical side of the central lengthwisedivision-wall.

At T is represented a shaft having its bearing-supports in the hub ofthe disk, and in the walls of the seed-box. On this shaft, within theseed-distributing chamber of the seed-box, the seed distributing-wheelis mounted to revolve therewith in such posit-ion that its peripheryshall extend through the slot N in the vertical division-wall 1*, and inits revolutions the stud-arms 0 of the pickers shall engage the guideand cam rims and the weighted le ver in such a manner that theseed-pickers in descending and passing through the seed contained in thechamber shall be limited in their openings to receive the seed properly,and in rising therefrom shall engage the weighted lever to cause thepickers to grip and hold the seed in its upward and over movement, andin its descent the stud-arms shall engage the irregular eccentriccam-rim to extend the pickers, causing them to open sufficient todischarge the seed and deposit it in the outlet-chamber, from which itdescends through the outlet-opening to .the ground in drills, orotherwise caused to be deposited in hills.

It will be noticed that the construction of the seed-pickers and theirpivotal connection with the seed-wheel are such that, in the revolutionsof the wheel, the action of gravity will tend to open the pickers toreceive the seed in their passage through the lower portion of theirrevolutions, and through the upper portion thereof the action of gravitywill tend to close the pickers, causing them to grip and hold the seed.By this construction, in connection with the guide and cam rims andpivoted lever, I am enabled to produce a reliable and efhcient seedingdevice at a small cost.

I claim as my invention- 1. A seed-picker, substantially as hereindescribed, consisting of the radial and segment arms with seedpickingbeak attached, as and for the purpose set forth.

2. The combination, with a recessed or chambered seed-distributingwheel, of a seedpicking device, substantially as herein described, saidseed-picking device having a pivotal connection within the chamberedwheel, and a seed picking and holding beak to grasp, hold, and deliverthe seed, substantially in the manner and for the purpose set forth.

3. The combination, with the seed-picking device having a pivotalconnection with the seed-distributing wheel, of a guide to limit theopening of the beak of the seed-picker, substantially as and for thepurpose set forth.

4. The combination, with the seed-picking device having a pivotalconnection with the seed-distributing wheel, of an eccentric cam to openthe beak of the seed-picking device to discharge the seed contained inthe beak, substantially as and for the purpose set forth.

5. The combination, with the seed-picking device having a pivotalconnection with the seeddistributing wheel, of a pivoted lever to engagethe seed-picking device to hold the seed within the grasp of the beak,substantially as and for the purpose set forth.

(5. The combination, with a seed-box, consisting of a seed-receptacle, aseed-distributing chamber, and an outlet-chamber, ot'the hereindescribedseed-distributing wheel mounted to revolve within thedistributing-chamber in contact with the seed contained therein, saidseed-distributing wheel having means, substantially as shown, adapted topick up and deposit the seed in the outlet-chamber, substantially as andfor the purpose set forth.
